WALL AND BLOCK FOR FOBMING THE SAME,

Application filed October 28, 1922. Serial No. 597,535.

T0 all wk0m it muy concern Be it known that ll, HUGH C. CARROLL, a citizen of the United States, residingat Mc- Keesport, in the county of Allegheny and State of Pennsylvania,have invented certain new and useful lmprovements in Walls 'and Blocks for Formin the Same, of which the following is a speci cat-ion, reference being had therein to the accompanying draw- 'scription which follows.

ln the accompanyiug drawings: Fig. 1 is a face view of a fragment wall cnstructed in accordance with the invention;

Fig. 2 is a front elevation of a block *made in imitation' of cobble-stone;

Fig. 3 is a face view of a block made in imitation of random rubble work;

Fi 4 is a horizontal sectional view through e part of the wall;

Fig. 5 is an end elevation of one of the A blocks;

Fig. 6 is a vertical sectional view through a part of a wall provided'with an interior air space; and

Fig. 7 is a detail sectional view showing the block used to face a wooden building.

Like numerals designate corresponding parts throughout the several figures of the drawings.

Broadly speaking the invention consists of a concrete block comprising a front por: tion and a rear portion integral with each other but with the front portion ofiset with respect to the rear portion so that one side and orie end of the front portion projects heyond the confines of the rear prtion, while the other side and end lies inwardly of the confines of said rear ortion. The faces of the outer portion of t e block are provided with a series of irregular grooves or channels in imitation of the division line between cobble-stone or rubble work and said ofl'set of a outer shape but conform to the adjacent or meetin'g edges of adjacent blocks and the blocks are so arranged that while they maybe laid in staggered relation to each other in the usual way in a wall, their meeting edges will )ortions of the block are irreglarly exactly match and when a heavy beaded Y pointing is applied to the grooves or channels in the .faces of the blocks and to the channels along the meeting edges between.

said blocks, the joint between the meeting edges is so concealed as not to be visible to an Ordinary observer. Thus the effect of expensive stone walls such as usually require the services of high priced artisan is secured through the medium of the employniehtot concrete blocks.

Referring now more particularly to the drawings, 5 designates the inner portion and 6 the'outer portion of a concrete block constructed in accordance with the invention. The edges of the inner portion are straight and said inner portion is rectangular in formation so that when laid up-in the wall these inner portions rest upon and engage one another much after the manner of an ordinary concrete block. The outer portions of the block are ofiset from the inner portions to leave a projecting side 7, a pro jecting end 8, a recessed side 9 and a reh cessed end 10,' the recessed end 10 of one block receiving the corresp0nding projections upon the projectihg end 8 of an adjacent block, and the recessed side 9 receiving the projecting portions of the two b locksnext below, it being understood that these blocks are laid in staggered relation in a wall to break joints in the usual way. A series of irregular grooves ll, 11= divides the blocks into irregular spaces in imitation of cobble-stone or rubble, as the case may" be, it being understood that these grooves are formed in the moulding or casting of the stpne and that the faces representing the faces of the cebble-stone or rubble will be suitably shaped in the mouldihg as by making it in reliet or intaglio as the case may be, to produce the desired efiect.,

After the wall has been laid up, a beaded pointing 12, usually of keen white cement,

though it may be of any color or any suitable material, is laid in the grooves 11, 11 and that pointing that is laid in the grooves at the meeting edges of the blocks is designedly spread enough to cover the joints between the -blocks and conceal them. To

i this end of the blocks are so formed as to lic compleder to accurately bring mentally in the adjacent blocks and the fin-.

ished. beaded pointin'g completely overlies the joint. To aid in forming an interlock between the several blocks, I preferably vrticallygr*oove the ends of the inner portion 5 of theblock, as indicated at 5*, and fill this space with cement mortar, indicated at 13. 4

From the foreg0ing it will be observed that the joints are broken between the several inner portions of the blocks. In other words these inner portions are laid up in staggered relation in the usual way. But in addition to that, the joints between the outer portions of the blocks are staggered with relation to the joints between the inner portions of the block, this being brought about by ofisetting the outer portions with respect to the inner portions in the manner indicated. This oflsetting of the outer portions withfrespect to the inner portions serves a further useful purpose in that the projecting surfaces 5" and 5 of the inner portions of the block, left by reason of the oftsetting of the outer portions, act as a guide or gauge in accurately positioning the blocks With respect to each other in the laying of the wall. In other words, in orthe projecting end of the outer portion of oneblock into engagemeht with the indented end of the pro- 3ecting portion of anotherblock, it is only necessary to lay the inner surface of the outer portion of the one block against the projecting surface 5 for example, and then slip the projecting end intothe recessed portion of the adjacent block.

ln the form of the invention illustratedin JF ig. 6 ilxhave illustrated a wall comprising an inner portion 15 made of ordinary concrete blocks and an outer portion 16 faced claim.

having bent ends which enter recesses formed in the tops of the blocks and which wall ties are embedded in the mortar joints between the blocks.

in Fig. 7 I.have illustrated the improved blocks of the present invention utilized to face a wooden building. In this case the facing blocks 17 are tied to the building by ties 18 having. downturned inner and outer ends, the outer ends being embedded in the mortar joints of the blocks and entering recesses formed in the tops of the blocks and the inner ends 'engaging in staples 19 driven into the wooden building.

It is to be understood that the invention is not limited to the precise construction set forth but that it includes within its purview whatever changes fairly come within either the-terms 'or the spirit Having described my inventin what l claim is:

A block of the character described oom prising an inner tion, the inner portion having its edges of the appended portion and an outer porln the form of the invention illustrated strai ht and rectangular and the outer portion aving its face irregularly channeled in imitation of the joints between a pluralit of irregularly formed stone, the edges df t e outer portion of the block being irregularly shapad and matching tact1ng portions of adjacent blocks and producing joints between adjacent blocks correspondmg in appearance to the imitation joints formed on the face of the block ]ln testimony whereof l[ hereunto afiix my signature.
